WEST SPRINGFIELD – Investigators continue to probe an explosion or fire in a Morgan Road shed that took a man’s life Wednesday night. The State Fire Marshal has determined the blaze, which broke out shortly after 10 p.m. in a backyard shed at 618 Morgan Road, was intentionally set.

“One person was involved and he was dead at the scene,” Sgt. Robert H. Porter said.

Police have not released the victim’s name.

Sgt. Paul Connor, a West Springfield police detective investigating the death, said that although neighbors reported an explosion, damage to the shed appeared to have been caused by fire.

The victim, Connor said, was found inside the burnt-out structure.

Jennifer Mieth, Spokesperson for the State Fire Marshal, said the fire remains under investigation, pending autopsy results. A state trooper from the state Fire Marshal’s office is assisting police in the investigation, Connor said.

A neighbor walking on Jensen Circle Thursday morning, who declined to be identified, said the home at 618 Morgan Road had been listed for sale for several months. Nobody had been living in the house, she said, but the owner had been regularly stopping by the property.
